IMPROVEMENT IN WIRE-BARBING MACHINES.

Specification forming part of Letters Patent No. 222,699, dated December16, 1879; application filed November 1, 1879.

To all whom it may concern:

Be it known that I, JOHN S. HAYNE, of Marshalltown, in the county ofMarshall and State of Iowa, have invented a new and valuable Improvementin Machines for Barbing Fenceires; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a representation of a perspective view of myimproved machine for barbing fence-wire. Fig. 2 is a per spective viewof the barb, and Figs. 3 and 4 are detached parts thereof.

This invention has relation to improvements in machines for attachingwire barbs to fencewires.

The object of the invention is to provide a machine that will quicklyand securely apply to a wire the barb for which Letters Patent of theUnited States No. 200,783 were granted .to me on the 9th day of July, A.D. 1877.

The nature of the invention will be fully set forth hereinafter.

In the annexed drawings, the letter A designates a base or platform,having suitable holes a, by means of which it is secured to the groundor to a support by means of suitable spikes, screws, or other equivalentmeans. Upon this base and supported thereby is an upright, B, which, asWell as the base, may be made, if desired,,of cast metal. Near the upperend of the upright is a horizontal slot, a, ending in a perforation, b,the main wire being introduced into said perforation through the slot toaforesaid. Above this slot, and pivoted to the upright B, are thegriping-jaws (l, composed of the lever-arms a, vibrating upon a pivot,d, and having their power ends connected by the toggle-jointed rods D.These rods are pivoted to the ends of the upper ends of the lever-arms cof the jaws G, and their remaining ends are pivoted to a lever, D havingits fulcrum upon the upright 13 or upon an offset arm, B, and balanced,or, if desired overweighted, by means of a weight, w, suspended by arod, to, or its equivalent, from the weight end of the said lever.Usually the perforation is made in a hard metallic block, 0, set intothe upright B, and communicating with the slot 11. aforesaid.

D indicates a hooked lever extending through a slot, f, at right anglesto the griping-jaws G, and having its bearings in a metallic plate, g,spanning said slot. This lever may, if deemed necessary, becounterbalanced or overweighted by a weight suspended from its end.

G indicates a bifurcated endwise-movable presser-foot, arrangedvertically in guides upon the upright B. This device is usually guidedby means of a bolt, g, extending through a vertical slot, 2', thereinand extending into the upright; but I do not design to use any specialform of guide, as many modifications of this construction are readilysubstituted for that above mentioned with equally good results. Thispresser-foot is connected by a link, h, to a vertically-vibrating lever,L, having its fulcrum on upright B, and balanced by a suspended weight,w.

The operation of this device is as follows, it being premised that thewire is wound up and paid off from a reel and passed through slot a intothe perforation b at the end thereof: The double-hook-form and barbpiece w is then passed on the fence-wire from below, and the straightpiece a." is then passed above the wire through the loops of part as.The hooked lever is then forced downward, causing its hooked end torise, and by clamping the loop y of part :10 against the upright B tosecure the said part as of the barb immovably in place. The griping-jawsare then brought together by depressing the lever D thereby clamping theloop g on the wire in the notch formed for the purpose therein from alateral direction, and leaving the points z separated. The presser-footG is then raised by depressing lever L, which presses the points of thepart- .r upward, causing the completed barb to present the appearanceshown in Fig. 2.

What I claim as new, and desire to secure by Letters Patent, is-

1. The wire-barbing machine consisting of the upright B, having the slotat the clamping-jaws O, the toggle-jointed rods 1), their QFFIGE.

operating-lever D the hooked lever D, the forked presser-foot G,arranged in guides on In testimony that I claim the above I havehereunto subscribed my name in the presence the upright, and a levermechanism operating of two witnesses.
